A benefit of the formulation is that the two part liquid EPDMformulation liquid rubber coating produced from the method is ambienttemperature curable.

A benefit of the formulation is the two part liquid EPDM formulation iseasy to apply in the field since it is a liquid and no heat source isneeded to cure the formulation.

A benefit of the formulation is that users of the liquid EPDMformulation produced from the method will avoid the possibility ofhaving second or third degree burns from applying the two partformulation, because the coating is “heat free” to cure on a substratewhich can be a roofing tile or flat roof base material. The formulationproduced from the method does not “hold heat” but reflects heat.

A two part liquid EPDM formulation produced from the method creates acured coating that has (1) waterproof sealing to resist hurricanestrength rainfall; (2) resistance to acid rain degradation allowing atleast 15 years useful life for a roof in an acid rain area (3) abilityto withstand cold temperatures of down to −50 degrees Centigrade, suchas Arctic weather.

A two part durable curable waterproof rubber liquid coating formulationproduced from the method does not require isocyanates or similar toxiccuring agents which are known to have a harmful effect on people asevidenced by allergic sensitization to isocyanates.

A two part durable curable waterproof liquid rubber coating formulationproduced from the method can be applied to existing roofs and existingsubstrates as a “cool white roof” material lowering the cost of buildingmaintenance, lowering the cost of energy, and reducing the dependence ofthe United States on foreign oil.

Schools, hospitals, public housing facilities, warehouses, residentialhomes, and facilities for the elderly, would benefit from a durablecurable waterproof liquid rubber coating formulation produced from themethod on the roofs of their institutions because the material willremain cool while simultaneously sealing the roof, providing areflective surface to reduce costs of energy and costs of maintainingthe facilities.

A cured material produced from the method can extend the life of a roof,reducing the need for roof replacement.

In other embodiments, a formulation produced from the method can be usedto seal docks for marinas.

A benefit of a durable curable waterproof liquid rubber coatingformulation produced from the method is that the formulation producedfrom the method is stable in its packaging system for delivery to auser.
